The Sloan Digital Sky Survey-III (SDSS-III) recently released the largest digital color image of the sky ever made, and it is free to all. The image has been put together over the last decade from millions of 2.8-megapixel images, creating a color image of more than a trillion pixels. This terapixel image is so big and detailed that 500,000 high-definition TVs would be needed to view it at its full resolution.

Penn State is one of three Pennsylvania institutions, along with the University of Pittsburgh and Carnegie Mellon University, that have scientists involved in SDSS-III.
